g4 lamp 12v Customers Reviews

  • Great replacement of 20W halogens

    posted by Pyuaumch

    These lamps are perfect replacement of 20W halogens - same brightness, same color temperature (maybe just a bit cooler).
    I wonder why it has "AC/DC" in specifications, it seems that these lamps work correctly only with DC voltage; with AC board elements get extremely hot and even smoking!
    Make sure your power unit outputs DC voltage, cause I had extreme overheating issue with AC unit.
  • Great white light

    I have used these LEDs in my outdoor lights. Despite the humidity and rain the LEDs still lights. Brightness is better than I expected and give good illumination of my garden paths also better than the old 20-watt halogen bulb.
    I have used these LEDs outdoors in an open lamp and with heads down, but the LEDs are not designed for this. Will you use it outdoors then it is best that they are protected from moisture. I can NOT promise you a long lifetime on the lamp if installed outdoors.
    Works fine and gives good light.
  • A moderate alternative for a G4 halogen bulb

    - Roughly the same size as a G4 halogen bulb- Much lower power consumption than halogen bulbs.- Fits perfectly in a breadboard
    - When replacing halogen bulbs with these leds, you might need to modify the power source. - Will look like 5 seperate light sources unless you use some kind of diffuser.
    It can replace a G4 halogen bulb, but it will look different
  • Good replace ment for 10w halogen bulb

    Good build quality, G4 = G4 so no bending of the pins is needed. Pins are larger and thinner then other LED pins so they fit easily.
    They have a little special effect that (for me) adds value: they replace 20 10 watt halogen bulbs and because there are 13 single leds on one light it gives a special effect when looking at the light: it has in total 260 light dots!
    Very good quality LED light, used to replace 10 watt halogen bulb. You may need to replace the trafo with a decent LED driver though as these LED use a small fraction of the power that a halogen bulb does.
  • Had to resolder leads, good amount of light output

    Decent amount of light output. Probably comparable to the halogen bulb, but definitely a bit warmer in color. Would buy it again.
    Reasonable replacement for the halogen bulb. Good light output. Used this to replace a burnt out halogen bulb in a couple of small desk lamps.
    Good replacement for a halogen bulb. Would buy again, but wished color was a bit cooler.
